that I experienced was several years ago on a flight from London to Stockholm where I was due at a business cocktail party in the evening. I arrived about 3pm but the suitcase didn't. BA traced it back to LHR and got it put on another flight (not sure if it was another BA or an SAS flight) and it arrived at my hotel by 8pm in the evening (after I had had to buy a new outfit for the evening). I didn't receive any compensation for the inconvenience of the loss - at the time I apparently didn't fit the relevant parameters.
Sorry you are still waiting - maybe someone else can help.
